Which of the following cell types in the epidermis is primarily responsible for producing the protein keratin?
A
Keratinocytes
B
Langerhans cells
C
Melanocytes
D
Merkel cells
Verified step by step guidance1
Understand the structure and function of the epidermis, which is the outermost layer of the skin. It consists of several cell types, each with specific roles.
Learn about keratin, a structural protein that provides strength and protection to the skin, hair, and nails. Identify which cell type is responsible for its production.
Review the role of keratinocytes, which are the most abundant cells in the epidermis. They are specialized for synthesizing keratin and forming a protective barrier.
Compare keratinocytes with other epidermal cell types: Langerhans cells (immune function), melanocytes (pigment production), and Merkel cells (sensory function). Note that none of these produce keratin.
Conclude that keratinocytes are the primary cell type responsible for producing keratin in the epidermis, based on their function and abundance.
